Geum plant named ‘Citronge’

ABSTRACT

A new, distinct  Geum  plant as shown and described, characterized by single orange flowers RHS color 24 B with wavy petals that overlap.

Latin name: Geum hybrid.

Cultivar name: ‘Citronge’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Geum plant named ‘Citronge’ characterized by single orange flowers with wavy petals that overlap. The new Geum was developed as an open pollinated seedling as part of a breeding and selecting program, at a nursery owned by the inventor in Helbron, IL. in 2008. The selection of the new plant was due to its' single orange flowers with wavy petals that overlap. The initial asexual propagation of the new plant was by division and took place at a nursery in Hebron, IL. in 2009. Continued asexual propagation by division since that time has shown that the unique features of this new Geum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart (2001). The new Geum plant named ‘Citronge’ is characterized by single orange flowers RHS 24 B with wavy petals that overlap.

The new Geum plant can be compared to ‘Sea Breeze’ U.S. Plant Pat. No. 26,437, flower colors are deep orange flowers of RHS 34 A while the new plant flower color is orange RHS 24 B. Flowers of ‘Sea Breeze’ also grow wider to 50 mm compared to the new plant flower width of 30 mm.

The new plant can also be compared to Geum ‘Totally Tangerine’ U.S. Plant Pat. No. 22,041, which is a sterile hybrid with lighter orange single flowers of 32 A, that fades to 169 C. Plants of Geum ‘Totally Tangerine’ also grow to 130 cm tall while the new plant only grows 33 cm tall at maturity.

The new plant can also be compared to Geum ‘Limoncello’ not patented, which has bright yellow single flowers of 9 A while the new plant flower color is orange RHS 24 B.

Plants of Geum ‘Limoncello’ grow shorter to 30 cm tall while the new plant grows 33 cm tall at maturity.
